I thought this book would be pretty super but it's a bit underwhelming. While a nice source book for practical tips and such, it doesn't really dig into the dirt of the matter: city garden design. Photos are pretty well done and they illustrate a great attention to detail, but they are not varied in terms of what's out there. It could offer a broader and more diverse perspective of garden design and landscape architecture. It reads more like a glorified portfolio - which is fine BUT then the purpose of this book should be to offer greater creative insight. The plant list offered while nice isn't really helpful. It'd be nice to have pix of the plants. Also, make sure you read up on the plants you want to use; some are considered invasive in particular zones. Grab a good plant book or talk to your nursery specialist.
There is one odd suggestion concerning gravel, on page 52, where it is recommended that you install gravel in a remote section of your garden because of the level of dust it creates, ending up in surrounding areas. The outdoors is full of dust and other matter, and I haven't seen where dust has become such a nuisance from this material that it warrants a warning like this. However, I would recommend some type of edging to minimize the amount of gravel which can be inadvertently kicked into surrounding areas.
Overall, a nice source book for tips with great detailed pix, but lacking in the diversity of design and detailed information.
